[0002] Safety test chambers are used in industries such as aviation, aerospace, shipbuilding, weaponry, electrical engineering, electronics, automobiles, motorcycles, and communications to determine the reliability of electrical and electronic products, instruments, or other equipment during transportation, storage, and use.

[0003] When conducting fluid contamination tests, different test pieces have different specifications and surface structures, which makes it impossible for some test pieces to be placed stably on the test platform. At the same time, some test pieces cannot be adjusted to different positions, resulting in certain spray dead angles during fluid spraying, thus creating contamination test dead angles. Utility Model Content

[0004] The present invention addresses the problem of providing a safety test chamber for fluid contamination testing. It solves the technical problem that when conducting fluid contamination tests, different test pieces have different specifications and surface structures, which leads to some test pieces being unable to be stably placed on the test platform, and some test pieces being unable to be adjusted to different positions. Consequently, there are certain spray dead angles during fluid spraying, resulting in blind spots in the contamination test.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safety test chamber for fluid contamination testing includes a test chamber body and a test chamber door. The test chamber door is installed on the outside of the test chamber body. A turntable is rotatably installed inside the test chamber body. A first electric push rod is installed on the bottom side of the turntable. A U-shaped seat is installed on the telescopic end of the first electric push rod. A rotating block is rotatably installed inside the U-shaped seat and is connected to a lifting seat. A fluid nozzle and a cleaning nozzle are installed on the inside side of the lifting seat. A base is installed on the bottom side of the inside of the test chamber body. A placement seat is installed on the base. Several limiting rods are slidably installed on the placement seat.

[0007] Preferably, a first motor is installed on the top side of the test chamber, and the output end of the first motor is connected to the turntable.

[0008] Preferably, a second motor is mounted on the U-shaped base, and the output end of the second motor is connected to the rotating block.

[0009] Preferably, the storage seat has several inner cavities, each containing a spring connected to a piston, and the piston is connected to the bottom end of a limiting rod.

[0010] Preferably, the base and the storage seat have a plurality of connecting air holes that communicate with the inner cavity and are connected to the outside.

[0011] Preferably, a second electric push rod is installed inside the storage seat, and a translation sealing plate is installed at the telescopic end of the second electric push rod, and a plurality of ventilation holes are provided on the translation sealing plate.

[0012] The beneficial effects of this utility model are as follows: the translation of the sealing plate is achieved by the operation of the second electric push rod. When the vent hole and the connecting vent hole are connected, the test piece is placed on the limiting rod. The limiting rod drives the piston to move in the inner cavity, compressing the spring and realizing the extension and retraction adjustment of the limiting rod. Then the translation sealing plate seals the connecting vent hole. The air pressure in each inner cavity is constant. The fixation of the limiting rod can limit and fix test pieces of any size and different sides of the test pieces, ensuring that the fluid on the test pieces can be sprayed in all directions in the future.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] See Figures 1-5 A safety test chamber for fluid contamination testing includes a test chamber body 1 and a test chamber door 2. The test chamber door 2 is installed on the outside of the test chamber body 1. A turntable 4 is rotatably installed inside the test chamber body 1. A first electric push rod 5 is installed on the bottom side of the turntable 4. A U-shaped seat 6 is installed at the telescopic end of the first electric push rod 5. A rotating block 8 is rotatably installed inside the U-shaped seat 6 and is connected to a lifting seat 9. A fluid nozzle 10 and a cleaning nozzle 11 are installed on the inside side of the lifting seat 9. A base 12 is installed on the bottom side of the inside of the test chamber body 1. A placement seat 13 is installed on the base 12. Several limiting rods 17 are slidably installed on the placement seat 13.

[0023] A first motor 3 is installed on the top side of the test chamber 1. The output end of the first motor 3 is connected to the turntable 4. The first motor 3 drives the turntable 4 to rotate, which in turn drives the fluid nozzle 10 and the cleaning nozzle 11 to rotate around the test piece. A second motor 7 is installed on the U-shaped seat 6. The output end of the second motor 7 is connected to the rotating block 8. The second motor 7 drives the rotating block 8 to rotate, which in turn adjusts the spray angle of the fluid nozzle 10 and the cleaning nozzle 11 on the lifting seat 9.

[0024] The storage seat 13 has several inner cavities 14, each containing a spring 15 connected to a piston 16. The piston 16 is connected to the bottom of a limiting rod 17. The base 12 and the storage seat 13 have several connecting vents 18 that communicate with the inner cavities 14 and are open to the outside. A second electric push rod 19 is installed inside the storage seat 13, and a sliding sealing plate 20 is installed at the telescopic end of the second electric push rod 19. The sliding sealing plate 20 has several ventilation holes 21. The second electric push rod 19 operates... As the sealing plate 20 is moved, when the vent 21 connects with the connecting vent 18, the test piece is placed on the limiting rod 17. The limiting rod 17 drives the piston 16 to move in the inner cavity 14, compressing the spring 15 and allowing the limiting rod 17 to extend and retract. Then, the sealing plate 20 seals the connecting vent 18, ensuring a constant air pressure in each inner cavity 14. The fixed limiting rod 17 can limit and fix test pieces of any size and different sides of the test pieces, ensuring that the fluid on the test pieces can be sprayed in all directions.

[0025] Working principle: The test piece is placed on the limiting rod 17 of the seat 13. At this time, the vent 21 of the translation sealing plate 20 coincides and connects with the connecting vent 18. The test piece acts on the limiting rod 17, which drives the piston 16 to move in the inner cavity 14, compressing the spring 15. After the limiting rod 17 is extended and adjusted, it drives the translation sealing plate 20 to translate through the second electric push rod 19. At this time, the vent 21 of the translation sealing plate 20 and the connecting vent 18 are staggered, and the translation sealing plate 20 seals the connecting vent 18. Each inner cavity 14... 4. The internal air pressure is constant, and the placement position of the limit rod 17 is fixed. The first motor 3 drives the turntable 4 to rotate, which in turn drives the fluid nozzle 10 and the cleaning nozzle 11 to rotate around the test piece. The first electric push rod 5 extends and retracts, which drives the fluid nozzle 10 and the cleaning nozzle 11 to move up and down. The second motor 7 drives the rotating block 8 to rotate, which adjusts the spray angle of the fluid nozzle 10 and the cleaning nozzle 11 on the lifting seat 9. The fluid nozzle 10 sprays fluid onto the test piece, and the cleaning nozzle 11 cleans the test piece.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
